Worldwide, efforts to slow down climate change are growing, and targets for reducing CO2 emissions are mandatory. The transport sector, which is globally responsible for more than 30% of CO2 emissions, has been forced to change its fuel. Thus, the electrification of the fleet is seen as an alternative to move towards an oil-free future. Considering the significance of effectively managing energy within microgrids for sustainable energy utilization, this article focuses on the study of energy management in a microgrid designed to facilitate EV recharges along highways. Considering the generations present in the MG, the energy tariff, and the demands for recharges, an optimization problem is formulated in which the objective is to choose the (dis)charge rates of the storage present in the MG. The results showed a preference for the sale of energy from MG to the grid in periods of generation greater than the local load. The storage charging/discharging events were limited due to process losses, restrictions in the optimization problem, and because the price of energy sent to the network via the net metering system was equal to buy.
